Not confirmed!
If the time horizon of 12 month and monthly measuring, as shown by
tiobe, is adequate, then the following holds:
For none of the top ten languages, except Perl, the hypothesis can be
falsified, that the measured values conform to a normal distribution.
Perl had a high plateau for 8 month, but lowered to the former niveau.
Notes:
1) The top ten languages hold roughly 80% of the "activity" shown by
tiobe. Seems that the 80:20-rule holds.
2) The least in the top ten, ruby, holds roughly 3% of the "activity".
Seems that the "no worth under 3% market share"-rule holds too.
I.e. all "activities" below 3% share might be equivalent to brownian
movement which might mask itself as an uprise:
